What is (2 + 0.4 + 0.6)= ?

Answer:
What is (2+0.4+0.6)
First we have to arrange the numbers in sequence...
[tex]2.0 \: + \: 0.4 \: + 0.6 \\ 3.0 \: or \: 3[/tex]
Here I have taken this 0 after the point ..as the rest of the digit are in tenths place or after the point...
The answer is 3.
We will not calculate the 0 as it does not have any value.
Ans) 3
